Abstract :
Special features of process control expert systems (PCX) make it both necessary and feasible to test them in a comprehensive manner. FAITH, an automated regression testing environment for PCX, integrates five specially adapted testing techniques, exploiting external specifications gained from the process control environment. FAITH also offers a set of metrics which can be used to predict testability during the early phases of PCX development. FAITH has been developed for a major German chemicals company where it is routinely used for certifying PCX, and for guiding design-for-testability
